APPARATUS FOR DRILLINTG AND THE LIKE.

Application flied April se, 19:52, semi no. 556,652.

This invention relates to apparatus for drilling and like operations,and particularly to holding means for such operations. Its main objectis to provide an apparatus which is adaptable for operations on avariety of pieces, and also to provide moans to facilitate theoperations of drilling and the like. Another object is to provide meansfor increasing production and for reducing labor in such operations.

In carrying out the above objects I provide apparatus 'which issubstantially uni-- versal in holding a variety of pieces to bemachined, and such apparatus includes a substantially universal frame,and one or more adjustable work-supporting means vhich are adaptable toa large number of pieces. I also provide tool-guiding means which can bemounted on the universal frame and changed from time to time to conformto different pieces. For increasing` production, the frame is providedwith two sets of work-supporting means, each of which sets may consistof one or several individual Work-holders, and there are also two setsof tool-guiding means, one for each riet of work-supporting means, sothat a machining operation can be performed on a part or parts in oneset while another part or set of parts is being removed and replaced byunmachined parts or blanks.

For accomplishing the above objects I prefer to employ the meansillustrated in the drawings accompanying and forming part of thisspecication, and in which-` Figure 1 is a .side elevation of my improvedapparatus for drilling and the like.

Like characters refer to like parts in all the figures of the drawings.

My improved apparatus may be mountedv on the frame of a drilling or likemachine in any suitable way, as for instance, on the table thereof. Thesaid table may be of any s itable form, such as that indicated by thenumeral 2 in Figs. 1, 2 and 3. The main portion of my improved apparatusis preferably a frame member suoli as that indicated by the numeral 3.Ordinarily the frame member has a base-plate such as indicated by l. andwhen used With an upright drilling machine, has an upright portion orportions such as 5. Preferably there are overhanging portions 6 at theupper part, which may be provided with openings or slots such as 7. Theframe member 3 may be mounted directly on the table 2, or may be mountedon intermediate portions, as illustrated in' the drawings, and suchintermediate portions preferably consist of two slides 8 and 9, at rightangles to each other, so that the frame and the parts thereon can bemoved to a great number of different positions in the same plane orlevel.

The frame member 8 is secured to the table, slide or other suitablesupport by any suitable means such as a pivot-pin 10, passing` through asuitable hole in the supporting member, and held fast by a nut 11. Tofacilitate turning, a ball-bearing such as 12 may be employed. Theupright portion or portions of the frame 3` are provided With verticalalining edges which are shown in Figs. 1, 2 and 6 in the form of T-slots13.

Any suitable work-supporting members may beprovided onr the frame forsupporting the blank partsto be machined, and I preferably employ angleblocks such as 14, which have alining portions 15 adapted to aline themin the T-slots 13. The said angle blocks are preferably movable upanddown in said slots and have bolts 16, 17, and nuts 18, by means of whichthey can be clamped at any height within the limits of the T- slot. Thenuts 18 can slide up and down in the said slots along with the angleblocks, and have suitable alining faces 19 to cause them to be alinedwith the sides of they T- slot. If desired, a spring-plunger such as 20can be employed to locate the blocks 14 in a given position in the slot.suitable holes 21 being placed in the upright Vportion While thework-supporting members are here shown as movable vertically into andout of drillingposition, they may, it de,- sired, move, in any suitabledirection, as for instance, in a horizontal direction, when used inmachines whose' drilling or working spindles are horizontal.

Suitable holding means for blanks are placed on the upper part of themember or members 14, and these are preferably of a form to tit the partto be held, as in Fig. 1, where the part to beA held. is a circularplate 23 having a hub. 24, and where the holding means embody a seatportion or b lock25 on. whiehtheplate 23 rests, having aimle 26 forthehub 24, a pin 27 for alining with. the holek in thehub and a clampingScrew 28; to. secure the hub 24. A wrench such asthesocket wrench 30 otFig. 9 is used tol tighten, the bolts 16, 17 and the.

clamping screw 28. To put a blank in position, the. bolts 16, 17, areloosened, and the.u member 14 is lowered, the blank put in. position.with. the hub in the hole 26, the screw 28 clamped on the hub, and themembre/1:14 moved up tothe position shown in Fig. 1 which is foundby thespring plunger 20.1neeting, the hole 21, and the bolts 16, 17, are thentightened by the wrench 30.

Suitable guiding means for drills and othercuttingtools are provided,ordinarily such means consisting ot. holes such as 33 in. the plate or.plates 34 mounted on the overhanging portions 6 ofthe frame 3, and heldby suitablemeans such as screws 35 and dowel. pins 36. A portion 37 oitsaid plate4 34 ordinarily extends down into the opening or slot 7, sothat thel tool-guides may be as close as possible to the blanks to bemachined. the holes willbein bushings 38- in the plate 34, asseenatl theright in Fig. 2,

Besides the work-holding means shown in Fig. 1, othermea-ns maybeemployed, as in- Figls. 4A 'and 5, where the seatV port-ion or block25 is provided with gibs 40 and jaws 41-movable insaidgib's by a rightand lett handlithreaded.screw 42-so as-to clamp the member 43 by its hub44. Blanks of other forms are readily held by changes inthe arrangementon the lseat portion or block 25, as .seenin Figs. 6 and 7j, whereaV-block 46 is secured to the block 25 and/a screwV 47,` in alug 48,clamps theblank 49, which is :dined at the sides by pins 50.y Also in 8the seat portion 25 has a groove 51, in, which the blank 52 tits, and issecured by aclamp 53 and a. bolt54.

The work-holder frame 3 can be turned abontvthe pin 10 bylooseningtheclamping bolts 57 and clamps- 58,r and pulling up and giving a `quarterturn on the spring-plunger In ordinaryusela set,of parts to be machinedare clamped in-proper position on the workesnpports 14-atlthe frontofvthe apparatus (on. the leftlside ot Fig. 1). The Vtrame 3l is thenturned -one hundred and For very accurate work eighty degrees to. bringthe blanks and toolguides under the drills D or other cutting tools, asseen at the right in Fig. 1. The spring-plunger G0. is then let downinto the hole 84, and the bolts 57 tightened on the spindle dri-llingormilling machines, and@ multi-spindle machines of the' same type; Itafour spindle type oit-machine is used, the. slides 8 and 9 are movedv bymeans ot' a crank or handwheel applied -to tl'ie-sha-nks of the screwsG4 and' G5, soas to shit-t the frame 3 anch parts thereon to differentpo`l sitions, employingthe pointers'70 andl scales 71, orspring-plnngers 75 andI holes-76 to locate suchv positions, and drillingorotherwisetmachining, four holes. or other-oper tions for each downwardn'iovement4 ot' thedrills or tools. It' the` drill' Aiced isl handoperated, one. operator will be required to attend` to it, and oneloperatorwill meanwhile remove drilled pieces and put fresh blanksinplace on-the work-supports at the 'front et the apparatus or at thelett side in Fig. 1. Substantially the samel method holds ior the. twospindle machines with slightly more shifting-ot the slides 8 and 9. Itthepmachine used is provided with a power feed, one operator canadvantageously attend to all operationsof'v placing and-removing blanks,and starting and stopping ther'eed-A ot'. the. tools, at-a greatl savingin labor cost andrelative increase of production.

It a. multiple spindle machine with power feed is used, thegreatesteiiiciency and economy can be obtained, asin thev work shown inFigs. 1, 2 andl, twenty-four holes can be drilledrin one setting, and ifthe holes are short in depth, two operators canlbe employed forhandlingl blanks, one of `whom starts theieed and'fotherwise controlsthe cutting tools.

lt will be noted that only a single trame member-3 is necessary forsupporting all sorts of blanks up to a certain-size so that- Iierm-thefra-me vuniversal in this respect, and Ialso term the `member 14 uponwhich are Imounted the means to secure the blanks. universal for asimilar reason. The said member 14' as described hereinbetore is adaptedto be lowered frointhe drillingposition, so that more room can be hadfor taking out and putting blanks into the seat portion, and it can beraised when' the blanks are in place, upto a position close under thedrill guides. The 4clampingbolts are madeA of a suflic'ient size toallow *it to be rigidly clamped in such position.

The layout ot the screw and pin holes inl dll the plates 34 isinterchangeable for all layouts of drill or tool-guides so that theframe 3 and the Work-suliports 14 are'used in common orare universal toa. large variety of drill-guide plates.

All the spring-plungers operate on the same plan, of which the plungernumbered yis representativel vand will be now described. The movablepart of said spring plunger `is indicated by 80, and moves up and downin a threaded bushing '81, secured tothe plate 4. A coil spring 82'isplaced between the collar 83 of the member y8() and the top part of thebushing so that the member is normally pressed towards the hole 84.There is a pin 85 on the member 80 which can pass up or down through theslot 86 in the top part of the bushing 81 when the member 80`is moved upor down, and when the member 8O is moved up and given a quarter turn itwill remain up by reason of the pin 85 resting on the top part of thebushing 8l.

Some operations can be performed in the above described apparatusWithout the aid of the tool-guiding means such as that in the plates 34.In such cases the said plates 34 are removed andthe apparatus used inall other respects as hereinbefore described for changes in position ofthe parts to be machined.

kIt is evident that the mere mechanism for giving the several movementsto the different parts may be modified and changed in various Ways, andany suitable forms of parts and arrangement thereof may be employedwithout departing from the principle of the invention, and I do nottherefore confine myself to the details of construction here shown.
